Abstract: The study was carried out in 2008 in 3 locations to evaluate the efficiency of Pastar® herbicide in the control of chirahui, vinorama and mezquitillo in buffel grass prairies at central Sonora. The following treatments were applied: 1) Pastar® 1.0% dissolved in water and applied to the foliage and 2) Absolute control without application. The herbicide was applied to the foliage to plants 1.6 m high. Changes in vegetation during 2008, 2009, 2012 and 2015 were evaluated and financial runs were carried out to determine the profitability of shrub control. Pastar 1% herbicide controlled 100% of the species in the 3 study sites and did not affect the native grasses or buffel grass. The density, height and basal cover increased (P <0.05) between 33.7 and 148.0% and the total pasture forage production varied from 1.42-1.68 in the control and 2.48-3.01ton DM/ha in the plots treated with herbicide. The animal carrying capacity increased between 144.0 and 211.9%. The financial runs to evaluate the profitability of the use of 1% Pastar® herbicide indicate that the grasslands rehabilitated by these means can produce additionally from 34.4 to 50.4 kg of breeding/ha and provide an extra net gain of $ 2,428.2 to $ 3,310.9 pesos/ha/year in comparison with the untreated check. It is concluded that the buffel grass pastures invaded by invasive shrubs require the application of control methods to recover productivity. It is economically profitable to use the Pastar® herbicide to rehabilitate degraded buffelgrass pastures.
